# Fixed Response Agent

The Fixed Response agent returns a pre-configured response with support for template variables. It substitutes placeholder variables with actual values at runtime, making it useful for generating personalized or context-specific responses. No LLM is involved -- the response is deterministic, fast, and cost-free.

## Use Cases

-   Generating **personalized welcome messages** with user-specific information.
-   Creating **templated email responses** with dynamic content insertion.
-   Providing **standardized responses** with variable data like order numbers or customer names.
-   Building **reusable response templates** for customer support scenarios.

## Inputs

Input

Type

Required

Description

`named_inputs`

Any (multiple)

No

Flexible inputs from other agents. Supports text responses, tool execution outputs, and primitive values (strings, numbers, booleans). Named Inputs take precedence over Extracted Variables when the same variable name exists in both.

`extracted_variables`

JSON

No

Key-value pairs to replace template variables (e.g., `{"name": "John", "orderId": "123"}`).

## Outputs

Output

Type

Description

`fixed_response_with_sources`

Text With Sources

The formatted response text with all template variables replaced by their actual values.

## Configurations

Parameter

Description

Default

**Fixed Response Template**

The template containing `{{variable_name}}` placeholders. Variables are case-sensitive and must match input names exactly. Supports HTML formatting tags (`<br>`, `<strong>`, `<em>`, etc.).

Required

### Template Syntax

Use double curly braces for variable placeholders. Variable names are **case-sensitive** -- `{{Name}}` is different from `{{name}}`. If a variable is not provided, the original placeholder is kept in the output.

```
Dear {{Customer Name}},

Your claim {{Claim Number}} for ${{Amount}} has been {{Status}}.

Thank you,
{{Company Name}} Support
```

## How to Use This Agent

Send an acknowledgment after a ticket is created:

```
ticket_trigger -> extract_entities -> fixed_response("Your ticket #{{ticket_id}} is confirmed.") -> send_email -> workflow_output
```
